Division in Equations


In this lesson, you will learn how to divide equations. In our previous lessons, we learned how to add, subtract, and multiply equations. Well dividing equations is pretty much the same thing except you will be solving equations with division. So let's start!

Division in Equations 

Remember that when solving equations, you just want to get the value of x, or in other words, of the variable.

x / 4 = 80

In order to solve the above equation you need to use the reverse operation. The reverse, or opposite operation of division is multiplication. So, we will multiply 80 by 4 or 4 by 80 ( it doesn't matter) and we'll get the product of 320.

That means the variable x equals 320.
We can check this by replacing the x with 320 and solving the equation.

320 / 4 = 80
So the answer or solution is correct!

x / 4 = 80
x = 320
